ABSTRACT
The primary objective of this study was to investigate the impact and most effective quantity of urea in the supplementation of ammoniated corn cobs on the digestibility of dry matter (DM), organic matter (OM), Neutral Detergent Fiber (NDF), and Acid Detergent Fiber (ADF) components in Brahman Crossbred cattle. The research utilized a Randomized Complete Block Design (RCBD) comprising of 3 treatments and 3 groups. The experimental treatments consisted of three groups: P0, which consisted of 80% basal feed and 20% untreated corn cobs (0% urea); P1, which consisted of 80% basal feed and 20% ammoniated corn cobs (2.5% urea); and P2, which consisted of 80% basal feed and 20% ammoniated corn cobs (5% urea). The data acquired were assessed utilizing Analysis of Variance at a significance level of 0.05. The variables under observation were the digestibility DM, OM, NDF, and ADF. The findings indicated that the use of ammoniation treatment had a significant impact (P<0.05) on the digestibility of dry matter for treatments P0 (54.33%), P1 (57.97%), and P2 (56.52%), organic matter P0 (57.56%), P1 (58.89%), and P2 (58.38%), as well as acid detergent fiber (ADF) digestibility P0 (49.08%), P1 (55.84%), and P2 (54.80%). However, there was no significant effect (P>0.05) on NDF digestibility for P0 (59.45%), P1 (63.06%), and P2 (63.22%). In summary, the inclusion of ammoniated corn cobs in the diet of Brahman Crossbred cattle has been shown to impact the digestibility of DM, OM, and ADF. The most effective level of ammoniation appears to be at a rate of 2.5% urea.
